Vaginal bleeding which may occur upon embryo transfer in IVF treatments is called luteal phase spotting. Luteal phase spotting occurs in different forms from patient to patient. Usually, it lasts for a few days. Most of the time, it occurs in the form of light bleeding. It is possible to see such light spotting 7-8 days after egg collection during IVF treatment. Time after embryo transfer is a waiting period for the patients. Waiting for the pregnancy test result is an anxious period. If spotting is experienced, the patient may think she will receive a negative result. However, the patient should not assume negative result if she experiences spotting as according to research there is no correlation between spotting and non-conception.
What is Luteal Phase?
Patients who experience spotting after embryo transfer can still receive positive results in pregnancy tests. There is no relation between these two incidents. In the regular menstrual cycle of women, after ovulation, a structure develops in the ovaries. This structure secret certain hormones which prepare a surface for the embryos to hold onto the uterus. This period in the menstrual cycle is called the luteal phase. If this phase never happened, no birth would happen on time and there would be continuous miscarriages. Embryo would not be able to hold on tight to the uterus of the mother-to-be. Therefore, luteal phase is very important for women. For healthy and positive results, formation of this structure and secretion of certain hormones is essential.
Luteal Phase during IVF Treatment
During IVF treatment, while the embryo is expected to hold onto the uterus, there may be bleeding. For this bleeding i.e. luteal phase, medical treatment can be applied. In IVF treatments, first of all, the ovaries are stimulated. However, when this stimulation is done via medication, it is a known fact that certain functions are lost. Together with the negative effects, medication may result in more than desired reduction in hormone levels. This may in return cause luteal phase spotting. Medication used for luteal phase spotting is exactly for that. This medication will give positive results in case of reduction in hormone levels. Furthermore, this medication have proven track record in increasing substantially, the chances of positive results in IVF treatments. When adequate supporting medicine is taken, spotting will be prevented. When correct dosage of medication is not taken, negative results can be obtained in pregnancy tests.
Supporting Medication for Luteal Phase
When adequate and correctly timed luteal phase supporting medication is taken, likelihood of obtaining positive results from pregnancy test will increase. It is a generally accepted principle that patient needs to start taking them before embryo transfer. Some other research mentions that it is unnecessary to use medication until after 6-12 weeks of positive pregnancy test result. However, research on this topic continues. What is critical in any case is taking the correct dosage. It affects pregnancy results directly.
What is the importance of Luteal Phase?
Luteal phase affects IVF treatment from start to end. Therefore, treatment should be supported by medication using the most appropriate method. Otherwise, negative pregnancy results can be obtained. Adequate dosage is very important. However, every treatment where luteal phase is experienced will not necessarily be unsuccessful. Use of correct dosage medication, lowers the chances of bleeding and increases chances of pregnancy. In cases of spotting, one should not think that treatment is not right. In some cases, oestrogen is added to luteal phase supporting medication. However, this does not necessarily lead to positive results. What is important is correct dosage.
